What is collision detection in 3D games?

Collision detection is a technique used in 3D games to determine when two or more objects intersect or collide.

Why is it important for gameplay?

It's crucial for creating realistic interactions, ensuring objects respond correctly when they collide, enhancing immersion.

What are some common methods used for collision detection?

Common methods include bounding box checks, sphere collision, and more complex algorithms like the Separating Axis Theorem.

How does it affect game performance?

Collision detection can impact performance, especially in complex scenes, so optimization techniques are often necessary.

Can you give an example of a game that uses advanced collision detection?

Sure! Games like 'Half-Life 2' and 'The Last of Us' use advanced collision detection to create realistic environments and interactions.
